Application filed October 19. 1905. Serial No. 283,414-

To a whom it may concern:

Be it known that we, DANIEL P. FAHRNEY,

and residents of Springfield, in the county of Greene and State ofMissouri, have invented a new and Improved Hose-Coupling for Cars, ofwhich the following is a full, clear, and exact description.

This invention relates to couplings for connecting the cars of a train,the purpose of the invention being to rovide efficient means forconnecting the airose and other hose which should run throu h the train.

The object of t e invention is to produce a coupling of simpleconstruction which will couple automaticall when the cars are brou ht toether an which will have a -desirab e fiexi ility, ada tin the devicefor the passing of curves an ena ling it to accommodate itself toroughnesses in the road-bed.

The invention consists in the construction 7 and combination of parts tobe more fully described hereiuafter and definitely set forth in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a vertical central section taken through two adjacent carsat the coupling and showing our hose-coupling ap lied t ereto.- ,Fig. v2is a bottom plan of the arts shown in Fig. .1. Fig. 3 is a horizontasection, u' on an enlar ed scale and passing throug the principa partsof the coupling, representin the .same in the act of coming together. fig. 4' is a side elevation of one of the parts shown in Fig. 3; but witha spring, to bejreferred to here nafter, represented as removed; and Fi5 is a section taken substantially on the fine 5 5 of Fig. 3.

Referring morelparticularly to the parts, 1 and Zrepre'seiit t eadjacent extremities of two cars, the same be ng provided with a couplin3 ofl an common construction. From t e underside of this cou'plin 3 wesup ort horizontally-disposed draware 4 an 5,the bodies of wliichlairedisposed lonitudinallv on the'centrafaxis "o'fthe cars and eneath thecoupling 3 as will bereadily understood! These bars 4 "and 5 'are notattached to ether, butfare'simply "supported,

respective y, from the adjacent parts of the coupling 3, so that whenthe cars are coupled together their ends lie adjacent. To the adj acentextremities of these draw-bars 4 and 5 we attach hangers 6. As shown inFig. 1, these han ers consist of bars bent to angular form, so t at eachpresents a horizontal arm 7 and a vertical arm 8. The horizontal arms 7are attached by pivot-bolts 9 to the under sides of the draw-bars 4 and5, as indicated. These hangers extend in opposite directions, so thatthe arms 8 thereof are disposed remotely from each other.

In the vertical arms 8 of the hangers open ings 10 and 11 are formed,the said openings being arranged in horizontal alinement with thecorresponding openings of the opposite hanger; n the openings 10 wemount the stems 12 of our coupler l3, and the rear extremities of thesestems 12 are formed with a return-bend 14, so that tails 15 are providedprojecting inwardly, and these tails 15 pass through the openings 11, asshown. These openings 11 are elongated vertically, so as to form slots;-To the adjacent extremities of the stems 12 coupling-heads 16 and 17 areattached, the construction whereof is most clearly shown in Figs. 3 to5. These heads consist ofmassive blocks. The head 16 is formed with aninclined forward face 18, so that it resents the appearance of a wedge.The orward extremity 19 is formed into a air of op ositelyrojectinghorns 20, which orm a sufistantial y V-shaped recess or throat 21'therebetween, the central axis of the said throat 21 being disposed in ahorizontal plane, as indicated most clearly in Fig. 4.

Near the rear face 22 of the coupling-head 16 the inclined face 18thereof is formed with a tongue 23, the same being tapered to itsforward edge 24,-so that it presents inclined faces 25. The side face 26of this tongue constitutes a continuation of the side face of the block16, the same being parallel to the opposite side face, as will bereadily understood. To the outer face 26 we attach a s ring 26*, whichprojects forwardly and in tiie direction of the o posite coupling-head17. The purpose of tliis s ring will a ear more fully hereinafter.Tiirough the tilbck or couplin -head 16 we provide orts 27, 28, and 29.'Fhe ports 27 and 29, which are disposed adjacent to the inclined face18, emerge upon the rear face 22 of the coupling-head, at

which point suitable nipples .30 are provided, facilitating theattachment of hose, as will be readily understood. These ports 27, 28,and

29 emerge'upon the inclined face 18, so as to form openings 31, whichare in alinement vertically, as indicated in Fig. 4. At a suitable pointin the under side of the block or head port 28, as indicated-most cleary in Fig. 3,

passes diagonally through the body of the lock or head and emerges atthe rear face 22,

at which point it is provided with a suitable nipple 33, facilitatingthe attachment'of hose,

- as will be readily understood.

' for'the attachment of hose.

against, these collars we The coupling-head 17 is substantially similarto the coupling-head 16, except thatit is of opposite or complementaryform. Opposite the throat 21 of the block 16 a tongue 34 is provided,which is similar in all respects to the tongue 23, already described.Opposite the tongue 23 a throat 35 is formed, which is similar to thethroat 21, the same being formed between projecting horns 36, as shownmost clearly in Fig. 1

formed, which emerge upon the inclined forward face 38 of the head atthe point 39, and these ports are adapted to aline, respectively, atthis point with the openings 31 from the ports 27, 28, and 29, referredto above. The port 37 in this case is situated to correspond with theort 28, which is the steam-port, and is provi ed, like the port 28, witha similar dr1pvalve 40. The ports 37 emerge upon the rear face 41 of thecoupling-head 17, at which point suitable nipples 42 are rovided To t eouter face 43 of the tongue 34 a spring 44 is attached, which is similarin form to the spring;

36, referred to above.

The manner in which the coupling-heads 16 and 17 come together is mostclearly shown in Figs. 1 and 2. As indicated, the inclined faces 18 and38 come together. The tongue 34 of the head 17 is received in the throat21 of the opposite head, while the tongue 23 is received in the throat35of the head 17. In this Wa a. very secure interlocking of the coup'ng-heads is brought about. In order to assist in maintaining anintimate union between the two the springs 44 and 26 are provided, thesame being bent inwardly toward their ends, as shown, so as to'exert aressure upon the opposite faces of the heads or this purpose.

- Near the rear portlo'ns of the stems 12 we provide collars 46, whichhave substantially spherically-formed outer faces 47. Pressin rovide'helica springs 48, which surround t e bodies ofthe stems, as indicated.The inner extremities of these springs thrust against the heads 16Through the body ofthe coupling-head 17 ports 37 are and 17 and tend toforce the same toward each other. As stated, the rear extremities ofthese springs 48 press against the collars 46 and normally maintainthese collars in the openings 10, which openings constitute seats orsockets for the same, as will be readily understood. From thisarrangement it should be understood that the shock of bringing thecoupling-heads 16 and 17 together is much reduced, as the springs absorbthis force. In.

this connection it should be understood that the tails 15 of the stemsoperate as guides in connection with the stems 12, enabling the same tomove rearwardly. At the same time the tails 15 have the additionalfunction of maintaining the heads 16 and 17in a plumb position.

As indicated in Fig. 1, the hose connections 49 for the steam, air, andgas are attached to the nipples on the rear faces of the couplingheads.

With the arrangement described evidently a very flexible connection maybe made between the hose andtthe adjacent cars. By reason of thepivot-bolts 9. the hangers 6 and 7 may adapt their positions for passingcurves. At the same time the springs 48 take up'any longitudinalmovement of the coupling-heads in a front or rear direction. In order tonormally maintain the couplingheads in a normal or mid position, Weprovide chains 50, which are attached to eyebolts 51, carried,preferably, at the bends 14 of the stems 12, the opposite extremities ofthese chains 50 being attachedto springs 52, which are carried by thedraw-bars 4 and 5, as shown. From this arrangement when the hangers 6and 7 are displacedlaterally, as in passin a curve, the springs 52 willbe extende and will return the hangers and stems imilar chains 53 arearranged adjacent to the coupling-heads, which attach to the ,same,respectively, by means of cyebolts 54,

the outer extremities of these chains being attached to s rings 55,carried by the under sides of the a jacent extremities of the drawbars 4and 5. These springs 55, of course, when extended by displacement of thecoupling-heads tend to return the same to their normal mid-position. Thefact that the stems 15 are carried in slots is advantageous,

inasmuch as it enables the coupling-heads to be displaced more or lessin a vertlcal plane, so that they will adapt themselves to inequalitiesin the road-bed or to sudden changes of grade.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1.
